Abstract

The invention relates to the technical field of environmental engineering, and particularly relates to a dual-aeration gained microbiological treatment method for industrial wastewater. The method comprises the following steps: 1) filtering wastewater; 2) carrying out air flotation treatment on the wastewater so as to remove oily impurities; 3) carrying out secondary filtering on the wastewater; 4) carrying out pH value adjustment on the wastewater; 5) carrying out heavy metal ion sedimentation on the wastewater; 6) neutralizing the wastewater; 7) carrying out first aeration on the wastewater; 8) carrying out ion exchange on the wastewater by using cation exchange resin; 9) carrying out biodegradation on the wastewater; and 10) carrying out second aeration on the wastewater, so that reusable water is obtained. The dual-aeration gained microbiological treatment method for industrial wastewater provided by the invention is stable in running, and high in production efficiency; through a dual-aeration process, a microbiological treatment step is significantly gained, so that the cost and time of the microbiological treatment step are effectively reduced, the efficiency of the whole process is improved, and the quality of effluent water is good and stable.

4) pH value adjustment is carried out to waste water;
5) heavy metal ion precipitation is carried out to waste water;
6) waste water is neutralized;
7) first time aeration is carried out to waste water;
8) by Zeo-karb, ion-exchange is carried out to waste water;
9) biological degradation is carried out to waste water;
10) carry out second time aeration to waste water, obtaining can reuse water.
Concrete, step 9) in add nutritious dose and composite fungus agent.
Concrete, described nutrition agent comprises starch, glucose, urea, Sodium phosphate dibasic, potassium primary phosphate and magnesium sulfate.
Concrete, described composite fungus agent comprises proteolytic enzyme, amylase, cellulase, lipase, nitrobacteria, lactobacillus and yeast flora.
Preferably, step 4) in pH value be adjusted to 7.0 ~ 8.5.
